General InformationWater sampling devices range from a bucket dropped over the side of a small boat to large water bottles sent toward the deep ocean seafloor on a wire. Probably the most commonly used water sampler is known as a rosette. It is a framework with 12 to 36 sampling bottles (typically ranging from 1.2- to 30-liter capacity) clustered around a central cylinder, where a CTD or other sensor package can be attached.
Relatively simple to use (rosette only)
Heavy to transport/deploy
May be very fragile
